Meng Lu, a 22-year-old female college student in modern times, accidentally slipped into the book.
In the book, she transforms into a cannon fodder female supporting character with the same name, living in the 1980s.
She is a fat girl weighing more than 200 pounds. She was plotted against, but accidentally got into a "fake marriage" with the battalion commander He Zheng, who is known as the "Living King of Hell".
The political commissar required the two people to pretend to be husband and wife for three months before they could release the news that they were "divorced."
Meng Lu, who came through the book, shoulders the wish of the original cannon fodder female supporting character. She needs to be self-reliant, repay He Zheng, and prevent him from being killed by the villain.
Trying to lose weight, learning to do business, and outsmarting villains, Meng Lu also grew up little by little in the process of completing her tasks.
Finally, Meng Lu, who successfully lost weight and became the "Queen of Pearls", was begged by He Zheng: "Meng Lu, let's be a real couple!"
